To simplify the design of Building Fire Water - Fire Water System Design, Building Fire Water, automatic fire - Fire Industry
The total cost of fire water supply system construction cost of 30% or so
, the paper investigates how to improve the fire safety project cost, more compact design the fire safety of water supply system. HC Fire Network With the newly revised "The People's Republic of China Fire Services Act," the purposes of fire safety design of building work will be independent, professional audit work will be more serious. Fire Water System Design will be with the new Technology , The use of new equipment continue to improve, security will be higher. This paper is designed to simplify the design does not mean lower quality, the total cost of fire water supply system construction cost of 30% or so, here is how to improve the fire of the project cost, more compact design the fire safety of water supply system. Also I hope this will give staff fire safety design of building to be a reference to the feasibility of practical application has to be further tested. 1, the purpose of simplifying the design Fire inspection of the writer, found that many buildings on fire water system design is unreasonable, although also to meet the specifications and use requirements, low cost and high costs. Example, there are both high pressure water tank water tank; fire pump frequency operation has been achieved, the system is still installing the pressure regulator pump pipe network stability; main pump, pump regulators are frequency operation, etc., by non-professionals with a repetitive construction chaos money sense. This paper is the maintenance cost savings and convenience of how to simplify the design of fire protection water supply. 2, used construction equipment, fire water supply Building Fire Water Project water from the fire water, fire water supply equipment, piping systems, interior fire fighting equipment and systems annexes. Fire Water Supply Equipment can be divided into: Automatic water supply equipment (fire water tank), the main water supply equipment (fire pumps), the temporary water supply equipment ( Pump adapter ), Local boosting equipment (pressure fire water supply equipment). Is combined with "architectural design code for fire protection," explained the work of three common principles of fire water supply equipment. (A) high fire water tank. That meet the specifications of the static pressure to meet the most negative points Fire Hydrant Water pressure tank, gravity gravity water supply, setting the highest office in the building, static pressure can not meet the most negative point of fire hydrant water pressure, the regulator should be set pressurization facilities. Temporary high-pressure fire water supply system must be set up fire water tank, fire water pressure systems usually only meet but can not guarantee that the fire water. Occur Fire When the fire by starting the fire pump to provide water. (B) Pressure water supply equipment. Pressure regulator is a common equipment, including pressure tank, regulator pump and some accessories. Work by air pressure tank into the form of qi type, capsule pressure fire water supply equipment, according to whether there Fire Pump Group is divided into ordinary fire with fire pump pressure water supply equipment and no emergency fire pump pressure fire water supply equipment. When the settings established by a high degree of fire water tank systems can not meet the most negative point of pressure needed to fire fighting equipment requirements, building fire water supply system should be set booster regulator device. The booster device can only pump, water pump and air pressure can also be tank, set the air pressure tank to reduce the frequency of pump starts. Pressure tank shall meet the minimum design pressure of the fire service water supply systems required for fire-fighting facilities, the work pressure. Including emergency pressure tank should be able to meet the initial 10min fire water, typically no regulator in the pump device. (C) Constant Pressure regulated water supply equipment. Including pumps and variable frequency control cabinet, using frequency conversion technology control the operation of pumps to achieve the purpose of stabilizing the pressure pipe. Transduce water control structures and the way diverse, more use of "Pump + Frequency control cabinet," the form of its excellent "constant variable" feature is a hit, the main function is as follows. (1) the primary function of pump frequency regulator. Usually no fire when the device is frequency stabilized voltage from the electrical contacts collection pipe network water pressure signal, when the pipe network under pressure below the regulated limit, fire pump frequency operation, the fire control net pay, when the tube reached the upper limit of Pressure regulator, fire pumps soft stop.To simplify the design of Building Fire Water - Fire Water System Design, Building Fire Water, automatic fire - Fire Industry
